Solidification behavior of water based nanofluid phase change material with a nucleating agent for cool thermal storage system

Study on the supercooling degree and nucleation behavior of water-based graphene oxide nanofluids PCM

“…Chandrasekaran et al (2014) investigated the thermal performance of nanofluid PCMs and the results evidently showed that the freezing duration was reduced by 25% in the case of nanofluid PCM along with the elimination of subcooling compared to that of deionized water. Li and Zhu (2009) devoted the experiments of CueH 2 O nanofluids.…”

“…In most published papers, additives contained in nanofluids are usually zero dimensional nanoparticles or one dimensional carbon nanotubes or nanowires (Chandrasekaran et al, 2014;Kumaresan et al, 2012;Shaikh et al, 2008). Graphene oxide nanosheet is a two dimensional material with many unique physical, chemical and mechanical properties, which may cause to quite different thermophysical properties from other nanomaterials (Wang et al, 2013;Heo et al, 2012;Tasviri et al, 2013;Mehrali et al, 2013).…”

Nanofluids revisited

“…DI-Water about 330 kJ/kg) can be stored or withdrawn without a change in temperature. Several contributions deal with nanofluids based Phase Change Materials [127][128][129][130][131][132]: Due to an increase of thermal conductivity, heat can be conducted more efficiently into the phase change material. This could help to reduce the necessary superheating or supercooling when initiating the phase change process.…”

Ice-dependent liquid-phase convective cells during the melting of frozen sessile droplets containing water and multiwall carbon nanotubes

“…Hordy et al [29] also demonstrated that surfacetreated MWCNTs remained stable in solutions undergoing boiling conditions. In solidification processes, MWCNTs have been reported to enhance the rate of nucleation, the speed of solidification and the total conversion of the base fluid, each of which increases the efficiency of the phase change process [30][31][32][33][34][35]. MWCNT nanofluids have thus shown great potential to modify the freezing and boiling processes of the base fluid, however their effects on the melting process have been relatively less described.…”
